I agree. That's exactly what I'm saying. I don't know why or it was deleted or by who, and that bothers me. I am not complaining about unpopularity. I think unpopular (or popular) ideas shouldn't be silently deleted by unknown people for unknown reasons. I think some moderator ought to check the history and see what happened (which is hopefully possible).

Deleting unpopular ideas is a much more common problem (bias) than deleting popular ideas. Both are bad though.

You guys, from your perspective, can regard it as something like "a critic posted some critical ideas. regular posters refuted his points in detailed argument". that's a great thing to keep a record of. if you see it that way, be proud or whatever. why delete it? i don't understand.

I can tell you it was deleted long enough after the discussion had ended that i was no longer checking for new comments. it wasn't deleted to shut the discussion up at the time. which makes it all the more mysterious. can anyone look up what happened?
